Description of drawings
Fig. 1 does not enter each module diagram with start-up system for vehicle has key.
Fig. 2 does not enter detailed block diagram with start-up system for vehicle has key.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
With reference to figure 1 Fig. 2, the related vehicle of the utility model does not have key and enters with start-up system and comprise: no key enters and start-up control device 1, startup/stop button 2, door handle electronic module 4, low-frequency antenna 5, car body controller 3 and key 6.Described no key enters with start-up control device 1 and comprises: single-chip microcomputer 101, input interface 102 starts stop button input module 103, LIN driver 105, low-frequency antenna driver module 106, a numeral output 107, standby power supply module 108, CAN transceiver 109.Described no key enters and start-up control device 1 built-in high frequency receiver module 104 and high frequency antenna, and described high frequency antenna directly is arranged on the pcb board.
Described input interface 102 is connected with door handle electronic module 4, after door handle electronic module 4 transmits a signal to input interface 102, single-chip microcomputer 101 control low-frequency antenna driver modules 106 drive low-frequency antenna 5, send low frequency random number signal to key 6, and send the low frequency carrier signal signal to produce low frequency electromagnetic field.Described low-frequency antenna 5 can be arranged at the driver door in the hand, in copilot's door handle, also can be arranged on boot and the bumper, can also be arranged on a plurality of positions in the car.Low-frequency antenna driver module 106 can drive each antenna 5 and send low frequency signal.Described low frequency carrier signal signal produces low frequency electromagnetic fields through low-frequency antenna 5, and key 6 is measured the magnetic field intensity of its positions, and is converted to high-frequency signal and returns to high frequency receiver module 104.Single-chip microcomputer 101 is also controlled high frequency receiver module 104 and is received the signal of encrypted random number that returns from key 6.Single-chip microcomputer 101 self also carries out cryptographic calculation to the random number signal, and whether the coded signal that comparison key 6 returns is legal.Single-chip microcomputer 101 is also judged key 6 positions by the magnetic field intensity that key 6 returns, and the result sent to car body controller 3 by digital quantity output module 107 and CAN transceiver module 109, if key 6 is legal, and be in appropriate position, then car body controller 3 is carried out the order of opening the door/close the door.
Described startup/stop button 2 enters with start-up control device 1 with described no key with described car body controller 3 and is connected, and is used to transmit push button signalling, and after startup/stop button 2 was pressed, no key entered with 1 pair of key 6 of start-up control device and authenticates.Described authentication mode is identical when judging the opening-closing door signal.Described no key enters and the coded signal of start-up control device 1 by checking key 6, and the position signalling of key 6, judges whether to need to change electric source modes.If the key authentication is passed through, then car body controller 3 changes main power source module according to brake/clutch engagement signal, GES, gear signal.Described main power source module is integrated in the car body controller.Described main power source module comprises 4 high-side driver signal: ACC controls, IGN1 control, IGN2 control, START control.Above-mentioned four control signals can drive car load power supply relay ACC relay, IGN1 relay, IGN2 relay, START relay.Change by to the car load power supply relay changes electric source modes.Described electric source modes comprises OFF pattern, ACC pattern, RUN pattern, START pattern.
The corresponding relation of power mode and car load power supply relay is as follows:
Preferably, described no key enters with start-up control device 1 inside and has standby power supply module 108.Described standby power supply module 108 has high-side driver signal: ACC control and IGN1 control.After described startup/stop button 2 is pressed, send simultaneously and export two identical signals simultaneously, one to main power source module (car body controller), one enters and the start-up control device to described no key, when main power source module just often, the electric source modes of system is determined that by main power source module standby power supply module is just followed the variation of main power source module and changed; When main power source module went wrong, standby power supply module at first can keep Last status constant, and the operation according to the driver decides new electric source modes again, thereby had avoided causing car load to run out of steam suddenly owing to the inefficacy of main power source module.As long as two power modules have one can work normally and just can guarantee the operate as normal of system, thereby have improved the reliability of system.
In one embodiment, after key 6 authentications are finished, before the ato unit, also comprise the engine anti-theft authentication.Single-chip microcomputer 101 sends request to engine management module EMS, engine management module EMS receives that the request back sends a random number to single-chip microcomputer 101, engine management module EMS and single-chip microcomputer 101 carry out cryptographic calculation to this random number respectively, single-chip microcomputer 101 also sends to engine management module EMS with the result of cryptographic calculation by CAN, engine management module EMS is the result of cryptographic calculation relatively, if both couplings, ato unit then, otherwise do not allow ato unit.
In one embodiment, use the antitheft base station of NXP PJF7992A chip, use the mode of single LIN and described no key to enter and carry out communication with the start-up control device as motor.Described no key enters with start-up control device 1 has LIN driver 105, and uses NXP TJA1021 as transceiver, and all control logics are realized by single-chip microcomputer 101.
